These results are in line with findings from other authors, who described a remarkable decrease in cell migration capacity in response to STI treatment in colon cancer, and indicate that the antiinvasive function of STI571 might at least in part be mediated by inhibition of Abi1 phosphorylation that impairs invadopodia formation by CRC cells [18,20,21]. Here, ABI1 is linked to colonic neoplasm.
